WATCHGABE.

Specification of Letters Patent.

Patented May 3, 1921-.

Application filed July 12, 1920. Serial No. 395,480.

To all whom it may concern:

Be it known that I, Lnwr LUBIN, a citizen of Poland, and a resident ofthe city of New York, boron h of Manhattan, in the county of New Yor andState of New York, have invented a new and Improved Watchcase, of whichthe following is a full, clear, and exact description.

This invention relates to improvements in watch cases, and moreparticularly to a watch case having an improved construction andarrangement of center or reflector and improved construction andarrangement of back center or movement frame which supports any shape ofmovement in any shape of frame, the back center or movement frame beingcorrespondingly shaped in accordance with the shape of the movement andthe case so as to cover or fill u spaces at the outside of the movementin t e case.

A further object is to provide an angular watch case such as isespecially adapted for use in connection with wrist watches having animproved construction and arrangement of parts which facilitate themanufacture and assemblage of the watch case and the accommodation ofthe movement and the result in a watch case which is neat and attractivein appearance, relatively economical to manufacture, and strong anddurable in use.

With these and other objects in view the invention consists in certainnovel features of construction, and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings- Figure 1 is a view in front elevationillustrating a watch case embodying my invention.

Fig. 2 is a rear elevation of Fig. 1.

Fig. 3 is a view in rear elevation showing the hinged back or cover ofthe watch case in open position.

Fig. 4 is an exag rated view in longitudinal section throng the watchcase with the movement and crystal removed.

Figs. 5, 6, 7 and 8 are views in elevation or plan illustrating the fourprincipal parts of my improved watch case.

My improved watch case comprises four parts; namely, a case front 1, afront center or reflector 2, a back center or movement frame 3 and acase back 4. In describing these parts, I am employing the terms bywhich they are ordinarily known in the trade.

The several parts 1, 2, 3 and 4 are shown of general oblong shape, butit is obvious that the invention is not limited to the precise shape ofthe case as I may employ any sha e desired.

he case front 1 is connected at one end to the case back 4 by means of ahinge 5 at one end of the case, said hinge comprising alined sleeves 6and 7 on the case front and back respectively, and a hinge pin 8positloned in said sleeves. The case front 1 is provided at its endswith strap or bracelet receivlng loops 9 which may be of any formdesired. The front center or reflector 2 is of the same shape as thecase front 1 and fits snugly within the same and is secured therein inany ap roved manner.

The case ront 1 has an opening 10 and the front center or reflector 2has an openlng 11 to expose the watch dial, but the opening 11 in thecase front in the center or reflector 2 is slightly smaller in alldimensions than the opening 10 of the case front so as to providesgroove or ledge 13 for the accommodation of the watch crystal 14.

Furthermore, it will be noted that the side portions of the front centeror reflector 2 extend beyond the edges of the case front so as toprovide flanges or extensions over which the case back 4 snaps orsprings tigptly into closed position.

he watch movement illustrated by the reference numeral 15 is positionedwithin the front center or reflector 2 with my improved back center ormovement frame 310- cated around the movement and having corner plates16 which fill in the corner spaces around the movement and hold themovement firmly.

It is to be understood that this back center or movement frame 3 will beexternally shaped to fit within the front center or reflector. 2 andwill be internally shaped so as to exactly conform to the shape of themovement and .cover all spaces in the watch case at the corners of themovement. For example, as illustrated in Fig. 3, the movement 15 to litin the watch case such as illustrated is ordinarily rovided with beveledcorners and the bee center or movement frame 3 has the corner lates 16of the shape-and size to fill in t'e watch case at the corners of themovement, hence, the

movement is securely held and the frame covers all spaces and provides aneat and dustproof adjunct to the watch case as will be readilyunderstood.

The watch case is provided with an opening 17 for the accommodation ofthe watch stem 18 and, as above stated, the case may be of variousshapes to accommodate movements of various shapes, the frame 3 being ofthe pro er size and shape to compensate for the di erences in shapebetween the case and the movement.

Various slight changes might be made in the general form and arrangementof parts tlescri bed without departing from the invention, and hence Ido not limit myself to the precise details set forth, but considermyself at liberty to make such changes and alterations as fairly fallwithin the spirit and scope of the appended claims.

I claim:

1. A watch case, comprising a case front, a case back movable relativeto the case front, a front center or reflector fitting snugly andfixedly within the case front and forming at the front a crystalreceiving ledge and at the back a case back engaging flange, a hingeconnecting the case front and the case back, and said case back adaptedto snap over the flange of the reflector.

2. The combination with a watch movement of general angular shape havingbeveled corners, of a watch case, and a movement frame fitting the watchcase and having plates at its corners fitting the beveled corners of themovement and covering the spaces formed thereby in the watch case.

3. A watch case, comprising a case front, a case back, a front center orreflector fitting in the case front and having an opening thereinslightly smaller than the crystal receiving opening of the case frontand extendin beyond the rear edge of the case front forming a flange orledge over which the case back snugly fits, and a back center ormovement frame fittin within the reflector and of an internal sfiape tofit around the movement to be positioned in the case.

LEWI LUBIN.
